Air compressor is a machine with a motor or engine that compresses air to increase air pressure or supply air. As basic industrial equipment, air compressors have been widely used in multiple kinds of industrial fields such as metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, and textile industry.

The power consumption of the air compressor accounts for 15% of the total power consumption. Most air compressors have obvious inherent technical weaknesses due to their structure and principle. The adjustment of the output pressure is realized by manually adjusting the opening of the valve. Its disadvantages are slow adjustment speed, large fluctuation, poor stability and low precision.

USFULL FU9000C Series VFD (Variable Frequency Drive) is a tailored solution to Air Compressor.

The speed of the air compressor motor is related to the performance of the air compressor. By precisely synchronizing the voltage and frequency control in the air compressor system, the use of frequency converters in the air compressor system can achieve actual motor speed control without changing the air compressor motor torque.

Using VFD, the air compressor unit should reach the minimum pressure required by the industrial machine as the set pressure. The frequency converter changes the compressor speed according to the fluctuation trend of the pipeline pressure, which saves the exhaust process of the air compressor and saves electric energy.

We have two solutions.

1. Frequency Converter for Asynchronous Air Compressor

2. Frequency Converter for PMSM Air Compressor

It is common that no matter how diligent you are, the air compressor would suck up a lot of power from the grid. In this case, you need to add a USFULL frequency inverter. What’s more, as USFULL specializes in producing and installing air compressor inverters, we can offer our customers not only high-quality products but also professional installation services.

USFULL frequency inverter supports communication protocols including Modbus-RTU, Profibus-DP, Profinet etc.

There is a strict ERP system to control each unit of raw material so as to provide customers with the best quality and considerate service.

We have IEC test reports and CE certificate to ensure quality, and provide 18-month after-sales service to ensure worry-free purchase.
